Abstract

See full text

A paper bobbin for winding yarn has an outer periphery provided with two annular protruding portions each adjacent to one of two ends of the paper bobbin respectively; since each protruding portion is protruded a height from the outer periphery of the paper bobbin, the two annular protruding portions may help the paper bobbin not only to lower the frequency of fiber breakage at initial stage of a yarn winding operation, but also to contribute to get a high quality of yarn and an increase in yield.
